A restaurant came up with a genius way to stop freeloaders from using their Wi-Fi

Anything for free Wi-Fi. Chung Sung-Jun / Getty Images Usually, the slow, tortured eye roll of a barista is enough to refrain from asking for the Wi-Fi password at a coffee shop. But at Yaya's, a Thai restaurant in San Antonio, Texas, the owners have taken things one step further.

A Reddit user name Joshua_Glock first first posted Yaya's Wi-Fi code this weekend, and since then, no one has successfully connected to the restaurant's network. While businesses boasting clever Wi-Fi passcodes aren't anything new (earlier this year, a Chinese restaurant made headlines after it made customers solve an equation to figure out its menu prices), the equation is proving impossible to solve, and subsequently driving Redditors to the brink of madness.

Over the course of the last four days, some 400 users have responded to Joshua_Glock's plea for help. While many comments accused the restaurant of trolling its customers, some earnestly tried to either solve or find the flaw in the intricate equation.

"This looks a lot like a summation of a binomial probability density function. I strongly doubt the divider between N/m should even be there," one user wrote. "Given the mistakes, it looks like something written by someone who doesn't understand what they're doing," added another.

Sure, it's possible that Yaya's version Will Hunting made a simple mistake on the proverbial chalkboard. But what might be more probably is that a disgruntled employee got tired of being asked for the restaurant's Wi-Fi password, Googled "impossible math equation," and kicked back while waiting for the frenzy to ensue.

Whether the math equation is ultimately solvable or not, there's some genius at work here for sure.
